WINDOW CONSTRUCTION.

Specification of Letters Patent.

Patented July 4, 1911.

Application filed November 8, 1910. Serial No. 591,226.

.To all whom it may concerni Be it known that I, ALEXANDER FROM- HOLD, a citizen of the United States, resid slizet metal, so that the area available for glass is reduced as little as possible by the frame members, while at the same time the construction is strong enough to withstand the superimposed weight and to resist wind pressures.

The invention is concerned particularly with the means for securing the window sashes, either fixed or swinging, in place in the frame, the object being to facilitate the manufacture and installation of such work while providing for strength and security.

The invention will be more fully explained hereinafter with reference to the accompanying drawing in which it is illustrated and in which- 1 Figure 1 is a View showing a portionof an extended window frame or casing embodying the invention as applied to fixed window sashes and to swinging sashes as well. Fig. 2 is a detail view in section on the plane indicated by the line 22 of Fig. 1, but on a larger scale and partly broken out.

The frame, as shown in the, drawing, comprises .vertical members a'and horizontal members 5 which form openings adapted to receive fixed window sashes, as c, and swinging sashes, as d. The formation and connection of the members of the frame are fully shown and described in another application for patent, Ser. No. 577,455, filed August 16, 1910, but will be described here in so far as may be necessary to enable the present invention to be understood. Each frame member, whether vertical or horizontal, is preferabl formed of a single, continuous strip 0 sheet metal folded upon itself so as to form, in cross section, a double rectangular cross, having a central portion a and, it may be, edge webs a and a in the plane of the central portion. For the purpose of the present invention, each member has two closely folded, projecting transverse webs a a and a, a on opposite sides respectively of the central body portion a Each horizontal member I) is formed in the same manner as each vertical member (I,

having likewise a central body portion and transverse webs with, it may be, edge Webs in the plane of the central body ortion.

It will be observed that each rame member comprises a continuous sheet of metal bent to form two projecting transverse webs on the same side ctnnected at their bases by the intermediate portion of the sheet, so that the webs are held rigidly in relation to each other and so that the webs of the sash, hereinafter referred to, may be made to overlap the webs of the frame member on either side as may be most convenient.

It is not essential that both the vertical members and the horizontal members of the frame shall have the transverse webs, since the sashes may be secured in place by means of the transverse webs of the vertical members or of the horizontal members, but it is preferable that both the vertical and the horizontal members shall be provided'with the transverse webs.

Each fixed window sash has on each edge, front and rear, closely folded, projecting webs 0 which are adapted tooverlap the corresponding transverse webs of the frame members a and 6, preferably embracing such transverse webs between them or being themselves embraced between the transverse webs, the assembling of the frame and sashes being readily effected as the structure is built up in place. When the sashes and frame have been assembled as described, the sashes are secured in place, against the possibility of accidental displacement through any cause, by bolts f which are passed through the overlapping webs. In the case of the swinging sashes, it is necessary to provide, for each swinging sash d, an intermediate frame 9 which is also provided, on each edge, front and rear, with webs g which cooperate with the transverse webs of the frame members a and b' in the same manner as in the case of the fixed sashes, already referred to, the holding of such intermediate frame in place being made still further secure by bolts 7 as before. The intermediate frame 9 is likewise formed of sheet metal and may be provided with flanges g and f perpen ieular to the plane of theframe, or 006 eration with corresponding flanges d an ii ofthe swinging sash, a weather tight joint being thus provided.

The improved construction permits the entire structure for any job to becbuilt completely at the factory, shipped knockedown, and assembled easily on the job, while at the same time a very light but strong and rigid structure is provided. Y claim as my invention:

1. The combination of a sheet metal. window frame member comprising a continuous sheet of metal bent to form two closelyifolded, projecting transverse webs on the same side, connected at their bases bythe inter- 7 mediate portion, and a window sash having at itsved'ge closely folded, projecting front andrear webs which overlap and fit closely upon the corresponding webs of theframe.

2. The combination of a sheet metal window frame member com rising a continuous sheet of metal bent to orm two projecting transverse Webs on the same side, connected at their bases by the intermediate portion, a window sash having at its edge front and rear webs which overlap the corresponding webs of the frame and bolts passed through the overlapping webs.

This specification si ed and witnessed this first day of Novemfir A. D., 1910. ALEXANDER FROMHOLD.
